only allow the leftmost source lane to turn to any destination lane. As
a future improvment, need to handle multiple explicitly tagged left turn
lanes, but this gets closer to reality, particularly helping some crazy
maneuvers along Mercer in downtown.

stage generation falling back, will iterate on that separately.

Add tests of a few interesting intersections. The results right now
aren't ideal, but this sets things up for fast iteraton.
lanes all lead to a single lane via left/right turn, and just keep the
left/rightmost lane.
Sanity checked at Rainier / S Massachusetts, and 23rd / S Massachusetts.
- Temporarily workaround snap_cycleways crash in Xi'an
- Fix interpretation of blank turn restrictions. https://www.openstreetmap.org/way/739621435 was missing a right turn, which was causing vehicles to do this crazy loop to go from Madison EB to Lake Wash SB.
- Ignore turn restrictions when they don't match the number of lanes. https://www.openstreetmap.org/way/428090702 and similar need some updating.
Regenerate all data, but give up on lakeslice running fully. Going to
sacrifice that one for a bit to get new roads imported.
We were drawing "pop-up" style buttons in several places, using
copy/pasted logic - which was simple enough when using a unicode glyph.
But we want to use a different glyph which isn't in our font. Further,
using an svg like this gives us finer grained control around the layout
around the button "handle" than we could get with just space characters.
clipping boundary. I don't remember why the more complicated thing came
about. This fixes a weird incoming border in SLU into an unreachable
intersection (which is more accurate) and doesn't seem to cause any
problems to normal or oneshot maps, with or without explicit clips.

Total scenario size from 385MB to 412MB, but that's not so bad, and this
seems worth it.

turn restrictions, we have to be a little careful how we sum up the cost
for the entire sequence, only rounding at the end.
multiple points. This was already handled when the roads went between
the same intersections, but I found a case in Ballard where the roads
are just really close to each other. Screenshot diff empty in Krakow,
but still related to #243
- Cut off the one-way markings before the end of the road, to stop stomping over turn markings
- Draw turn arrows to every road, not each lane
- Only draw turn arrows when a lane is restricted from going to some
outbound lane. At most intersections, all turns are legal, so don't draw
anything.

that's a little trickier.)

anything.

in downtown, and per screenshot tests, doesn't have regressions
elsewhere. Also improves a few cases in montlake.

and also the lakeslice scenario to gridlock (a regression that began a
few weeks ago). But keep the flag on for now, to keep the montlake
scenaro running at least.
https://dabreegster.github.io/abstreet/trafficsim/gridlock.html has
notes about the many different causes and in-progress fixes for
gridlock. This experiment hasn't been explained very well yet, but
roughly it treats a cluster of traffic signals as one, so that once a
vehicle gains access through the first light, they guarantee immediate
access through the entire sequence. This interacts with the "don't block
the box" behavior (don't start a turn if you might get stuck in the
intersection) strangely.
While attempting to get this rollback to work, I also had to manually
redraw the traffic lights for a few manually specified intersections.
They became out-of-date a few weeks ago when I cleaned up the OSM
geometry upstream and the referenced IDs changed, and I hadn't bothered
to re-time the signals. Luckily, with the new multi-signal editor,
redrawing the timing was much easier than originally!
Regenerated all data and lots of bus routes vanished. Plan to get back
to that project soon.
